Abstract

The invention discloses a wedge side flanging device and a cold stamping die and belongs to the field of manufacturing. The wedge side flanging device is fixed between an upper die body and a lower die body and comprises a pressing plate, slotting tools, a lower die, flanging mechanisms and slide grooves. The pressing plate is fixed on the upper die body. Each slotting tool is fixed on an upper die seat. The lower die and the flanging mechanisms are fixed on the lower die body. Each flanging mechanism comprises a drive part and a flanging cutter block, and the cutter block is disposed below the pressing plate. Each slotting tool and each drive part are disposed on each of the outer sides of the pressing plate. By the wedge side flanging device, side flanging of side flanges of beam parts can be completed conveniently. In addition the wedge side flanging device has the advantages that the wedge side flanging device is exquisite in structure, simple in manufacturing process and high in practicality, subsequent maintenance is facilitated, and subsequent maintenance cost of dies can be lowered effectively.

Description

technical field [0001] The invention relates to the field of manufacturing, in particular to a pull wedge rollover device and a cold stamping die. Background technique [0002] In today's increasingly fierce market competition, all enterprises are faced with the problem of how to survive and develop sustainably, and adopting technological innovation and equipment improvement and upgrading to reduce production costs and improve work efficiency is the most direct and effective development direction. [0003] In the process of new product development, the cost of mold development accounts for a relatively large proportion. How to save the cost of mold development to the greatest extent is an important research topic for OEMs and mold manufacturers. [0004] Cold stamping die is a kind of mechanical equipment widely used in the manufacturing industry. The wedge rollover mechanism is an important part of the cold stamping die. Due to the space limitation of the installation of t...
